Really Simple SSL Pro: worth it for security, not just SSL
Really Simple SSL Pro is worth paying for when you want one dashboard for mixed-content repair, firewall controls, hardening, vulnerability alerts, and login protection. It is not worth buying solely to enable HTTPS: the free plugin or your hosting provider usually handles redirects, and alternatives such as Wordfence may offer a more established security-first approach.

Wordfence Security Premium: worth paying for faster threat protection
Wordfence Security Premium is worth paying for on business, membership, WooCommerce, and high-traffic sites where faster firewall and malware-signature updates, premium support, and centralized monitoring have real value. It is not a compelling upgrade for a small, low-risk site that can use the capable free plugin and keep WordPress updated; the premium features add protection, but they do not remove the need for backups, hosting security, or competent maintenance.
